Mea Mea Hana Coil Loaʻa maikaʻi loa a hale hana

Loaʻa i ka Coil

ʻO ka wehewehe pōkole:

I loko o ka'ōnaehana MRI, he mea nui ka coil e loaʻa ana, e pili pono ana i ka maikaʻi o ke kiʻi. Loaʻa i nā coils ke kuleana no ka ʻike ʻana i ka hōʻailona MR. Hiki ke hopu ʻia ka ʻupena mākēneki oscillating mai ka ʻōnaehana wili ʻoliʻoli e ka wili kahi i hoʻokumu ʻia ai kahi au uila. Hoʻonui ʻia kēia manawa, hoʻopili ʻia, a kānana ʻia e unuhi i ka ʻike alapine a me ka pae.

ʻAno:

ʻO ka wili ʻili, ka wili volume, ka wili transceiver

Ka pinepine:

hoʻopilikino ʻia e like me nā mea kūʻai aku

Kānāwai:

kanal hoʻokahi, kanal ʻelua, ʻehā kanal, 8 channel, 16 channel, etc.

kū'ē komo:

50Ω

Kaʻawale:

ʻoi aku ka maikaʻi ma mua o 20dB

Loaʻa preamp:

30dB

Kiʻi walaʻau:

0.5-0.7

Ka bandwidth hana:

1MHz, Hāʻawi i ka hana maʻamau

Ma hope o nā makahiki o ka noiʻi ʻana a me ka hana ikaika, ua hoʻomohala ka hui R&D o kā mākou hui i kāna coil loaʻa ponoʻī ma o nā hoʻokolohua pinepine a me ka hoʻohālikelike ʻana, a ua hōʻea kāna mau hōʻailona hana i ka pae alakaʻi o ka ʻoihana.

Loaʻa iā mākou nā ʻano coils he nui e koho ai, hiki ke hoʻokaʻawale ʻia e like me ka hiʻohiʻona, hiki ke hoʻokaʻawale ʻia i loko o ka ʻili, ka manu manu, a me ka transceiver coils. Eia kekahi, hiki i ka mea hoʻohana ke koho i ka helu o nā kahawai o ka coil e like me ka mea e pono ai,

ʻO ka mea maʻamau, ʻoi aku ka nui o ka hoʻohana ʻia ʻana o nā coils manu, a hiki ke hoʻohana ʻia ma ke poʻo, ka ʻāʻī, nā kuli, a pēlā aku; no ka laʻana, ua haku ʻia ka wili manu ʻelua-kanal i nā wili solenoid a me nā wili noho. Loaʻa i kā mākou coils nā mea kiʻekiʻe kiʻekiʻe a me ke kūlike maikaʻi, Hiki ke hoʻokō i nā ʻano pono scanning, i ka manawa like, hāʻawi pū mākou i nā lawelawe maʻamau, hiki i nā mea hoʻohana ke koho i ka nui iā lākou iho.

Hiki ke hoʻohana ʻia ka coil surface e nānā i ka spine a i ʻole nā wahi hoihoi; i ka hoʻohana ʻana i ka coil surface, ma muli o kona wehe ʻana, hiki iā ʻoe ke nānā i ka wahi hoihoi i nā posture like ʻole.

ʻO ka transceiver coil kahi ʻano hou o ka coil. Hoʻohui ʻia kona hoʻouna ʻana a me ka loaʻa ʻana, no laila ʻoi aku ka liʻiliʻi o ka nui o ka coil ma mua o nā coils maʻamau. Ma lalo o nā kūlana like, i hoʻohālikelike ʻia me ka ʻōnaehana hoʻokaʻawale transceiver maʻamau, loaʻa iā ia nā koi liʻiliʻi ma ka mana o ka mana RF power amplifier. Eia kekahi, ma muli o kona liʻiliʻi liʻiliʻi, ʻaʻole ia e koi i ka nui o ka wehe ʻana o ka magnet nui, a hiki ke hoʻohana ʻia no ka ʻōnaehana liʻiliʻi a i ʻole nā ʻōnaehana ʻē aʻe me nā koi ākea koʻikoʻi.
